Article Summary
NASA’s twin Radiation Belt Storm Probes (RBSP) took a musical interlude and listened to the Earth singing to itself. This “Earthsong,” as NASA calls it, was recorded by the two spacecraft as they orbited inside the highly radioactive Van Allen Belts that surround the Earth. The “song” is in the form of radio waves generated by the belts and the study of it may provide a clue toward answering the question of how to protect satellites and astronauts from deadly radiation storms.
